To all whomy 1' t may concern Be it known that MARKDCNOWLTONJate a citizen ot the United States, and resident of Rochester, Monroe county, State of New York, now deceased, did invent certain new and useful Improvements in Box-Covering Machines, of which the following is a specifieatioir.

'lhisinvention relates to that class of inach-ines adapted for applying a covering strip of paper or other material to paper or strawboard hoXes and the like.

Machines of this class usually comprise a inain supporting frame upon which are supported ,inpi'oper relative positions, the reel v1to1' carrying the covering-strip, the means for rendering the Stay-strip adhesive, the rotatable carrier for the box-form on which the boxes to be covered a rc placed, the guides for directing the covering-strip from the reel to the luix-ioriii. the cut-o'. for severing the covering-strip into proper .lengths for the. vboxes to be covered, and the mechaiiism for actuating the box-forni carrier and the cut-oil".

actuating mechanism are the parts most sh'hject to wear and consequently the parts most and it has therefore been onev otythe .maifii objects oty the present inventionto improve this class ofinacliincs by associating the box-form carrier and the cut-*oit with their actuating mechanism inthe .toriuot an attachment that may be readily attached to or detached from the traine of any usualy forni of boxcovering machine.

Another important object of the invention is to improve this class of `machines by rendering the boit-.forni carrier and the cutoii capable of any desired adjustments to meet the requirements of either the work or the operator, and by justmeiits to he etiected in a simple and easy manner. y

lith the foregoing and' ether objects in view, which will appea-ras the description proceeds. the invention resides, first, in the article of manufacture, of an attachment, comprising lthe boit-forni carrier and the cut-ott' with their actuatingr mechanism, .that may b'e readily attached Of: these several elements the; box-forni carrier and the. cut-ott with .their permitting suoli ad-v to or detached from the :trame of any usual box-covering machine; second, in the provision of means for permitting' the box-forni carrier to be adjusted in a direction longitudinally of ythe cutters, whereby the boxorin and supported box maybe brought to a position in line with the covering strip at whatever point it is advanced from between the cutters; third, in the provision of a simple and efficient mechanism for operating the box-form carrier and cut-ott;` fourth, in the provision of a` simple and efficient means for permitting pivotal and longitudinal adjustments' of the holder -for the' box-form carrier; and fifth, in the provision of counter-balance means for facilitating the ad-v justment of the cut-off.

The invention also-resides in certain other fea-tures of construction and combinations of parts all to be hereinafter referred to in the `detailed description of the invention which follows:

Any snitalile means ma); be 'provided for looking the said holder E in adjusted position; 'a single means preferably being provifjled that operative at one i i.. ation to eifeet the loeliing nl' the holder witl'i respect to both its pivotal and sliding adjustments. The ine-ans provided in thepresent oase for suoli purpose comprises a bolt G3 mounten-lin the pivotal (ir-oscillatory snpport 59, with one end, extending through a` segmental or aie-slnnied slot 6ft in the frame B and having a head or nut (i for engagement with .said traine, and its other end carrying a retaining member 66 for engagement with the bar 62, and a Clamping member in the forni ofk a lever-nut 67. VBy

loosening the elinnpin'i' niember 67, the support 59 may be `rof` d o'r oseillated about the shaft 2 to permit ot' an upward or downward pivotal movement of the holder E with respect to the eut-oil' C, and the said holder E may be given a sliding longitudinal movement on the support 59 to permit of its adjustment in a generally horizontal plane toward and from the eut-oli (fl. By tightening the clamping member o7, it will coiiperate with the nut (S to elai-n p the inter )osed parts and lock the bar (bof the hol er E against sliding movement on the support 5l),

' and also lock the support 59 in connection with thet'raine B against pivotal or oscillatory n'imeinent on the shaft 2.

V The means for ,mounting the box-form. earrier D upon its holder It includes a bracket 71 attached to one end of the hai4 (32 oit said holder, as shown particularly in Fig, 3, and having a journal-bearing 72 in which is rotatably mounted a. sleeve or hollmr shaft 73 adapted to reeeive therethrough the attaching s )indie of the box-form Carrier; the sai( spindle 70 being adapted to be adjnstably coupled to the shaft 73 in a manner to be hereinafter referred to.

The means vemployed in th. presentease for rotating the shaft 7 3 and connected boxforln carrier from the mainshaft 2, oomprises a bevel-gear 7.4-, fixed on the shaft 7 3, and meshing with a gear 75, fined on a Shaft 76, which is mounted in bearings 7 7, 77, eonneeted to the bar 62 of the holder E. Splined or keyed on the sha-ft 76 is a worm-gear 7 S which, as shown in Fig. 6, is `eonstantly in mesh with the worm 19 on the iii-ain shaft ,Q to be operated theiefrom, the said woringear 7 8 being splined on the. shait 7 (l to pormit longitudinal movement, ot the latter Vwith the holder E, and being held in mesh with the worm 19 by means of 4two oppositely-engaging bracket sleeves 79. 79', connected tothe pivotal support With this described combination of par it will be understood that the worin-.Gear 78 will impart rotation lo the shaft 7h from the worm it) von-thr main shaft 2, and at the same time permit of any desired longi ludiual adjustment ot the holder .l and fonneeted parts relative to said worm-gear. 'l`lnA gears 7S and QQ, as shown, are pre erably inelosed in easings 8O and Si respectively. the said easing's being formed with exiting-'ions Si) arranged with one exti'fnding [wisely into the other tio-provide a easing 4tori'he intermediale worin lll.

For the purpose of permit-ting the boxv torni carrier D to be adjusted in a direction longiti-idinally of the cutters, the spindle 70 of said carrier, as more clearly shown in Fig. 3, extends loosely through the hollow shaft 73 and is provided with a oued busliing or expanding block 83 splined thereon, with which cooperates a hand-wheel 84 that is threaded 0n the end of the .sl at'l' 7 rl AFor engagement with Said expanding block. By loosening the hand-wheel 84, the spindle 70 of the box-forni carrier, together with the supported box-forni, can be adjusted laterallv on the holder E 'in a direction longiiudinallv of the eut-off, and by lightening .the hand-wheel 84 so as to force the expanding block S3 into the end of the hollow shaft 73, the spindle 70 can be locked securely to the shaft 73 so as to rotate therewith, The advantage of having the box-forni earriet adjustable in a direction longitudinallui ol' the eut-od' is, first, that it enables the operator to readily bring the box-form to any position opposite the eut-olf at which the covering-strip may be advanced therefrom; and second, that it also enables the strip to he brought between the cutters at the sharpest portions of the same, y
